Percolation: The movement of water through the subsurface soil layers, usually continuing downward to the groundwater or water table reservoirs.
Perennial stream: One that flows all year round. Compare intermittent stream.
percolation (of soil water)
The downward movement of water through soil; specifically, the downward flow of water in saturated or nearly saturated soil at hydraulic gradients of 1.0 or less.

Percolation
1. The movement of water downward through subsurface soil layers, usually continuing downward to ground water level. Can also involve upward movement of water. 2. Slow seepage of water through a filter.

percolation 1) The slow seepage of water into and through porous media, such as soil in the ground. 2) The slow passage of water through a filter medium.

PERCOLATION POND: A pond that allows water to percolate (or seep) through layers of rock and gravel. The water is cleaned as it slowly travels downward and eventually reaches an underground aquifer.
Percolation: (1) The movement of water through the openings in rock or soil. (2) The entrance of a portion of the streamflow into the channel materials to contribute to groundwater replenishment.
Percolation. The downward movement of water through the soil or alluvium to the groundwater table.
Permeability. The capability of soil or other geologic formations to transmit water.
Percolation: movement of water through soil or rock.
Permeability: capacity of soil, sediment, or porous rock to transmit water.
Percolation
The downward flow or filtering of water or other liquids through subsurface rock or soil layers, usually continuing to groundwater.

percolation (PURR-ko-LAY-shun). 1) The slow seepage of
water into and through the ground. 2) The slow passage of
water through a filter medium.
Percolation of water through the soil from unlined canals, ditches, laterals, watercourses, or water storage facilities.
Selective Pesticide
A chemical designed to affect only certain types of pests, leaving other plants and animals unharmed.
Infiltration - the downward entry of water into the immediate surface of the soil, as contrasted with leaching (percolation),
which is the movement of water from the soil.
Irrigation - application of water to soils to assist in plant growth.
This includes the following discharge methods; absorption beds, injection wells, drainfields, percolation ponds, rapid infiltration basins, spray fields, and land application systems.
The process by which water is added to a zone of saturation, usually by percolation from the soil surface; e.g., the recharge of an aquifer.

Most are pond systems that dispose of the total flow they receive by means of evaporation or percolation to groundwater, or facilities that dispose of their effluent by recycling or reuse (e.g., spray irrigation or groundwater discharge).
A shallow excavated channel backfilled with gravel and designed to provide temporary storage and permit percolation of runoff into the soil substrate.

Leachate Water that contains solute substances, so that it contains certain substances in solution after percolation through a filter or soil.
(2) The circuit of water movement from the atmosphere to the earth and return to the atmosphere through various stages or processes such as precipitation, interception, runoff, infiltration, percolation, storage, evaporation, and transportation.
from the soil into sewer or other pipes through defective joints, connections, or manhole walls. 2. The technique of applying large volumes of wastewater to land to penetrate the surface and percolate through the underlying soil. (See> percolation.) ...
